| description | The paper considers the role of vertical snowpack structure for snow avalanche formation and describes the idea of «structural instability». It aims at enhancing the knowledge about transition mechanisms between stable and unstable states of snowpack and snow avalanches release. Structural instability implies the presence of weak layer or interface in vertical snowpack profile. Type of snow failure and avalanche characteristics are completely defined by snowpack state and properties. Thus wide variety of genetic types of snow avalanches indicates the existence of structural instability of different types. The detailed analysis of scientific publications and field observations led to the creation of a new classification of weak layers. The layers are classified basing on their cohesiveness, the causes of initial disturbance and internal and external processes which form a weak layer. The classification is a necessary part of global method which allows assessing snowpack stability using modern physical models of snow cover evolution. |
